I've got a few bits to sell:
Front Brake rotors: In good shape, from a late 80's K with 47K miles. Non-ABS. Will get the thickness this weekend. $150 + Shipping (likely flat rate box. Whatever is cheapest)
Wiring harness for K75, K100. Square instrument cluster plugs, iirc. Good condition, includes all but 2 of the spst relays. Can replace those from any auto parts store, and they rarely fail. I think its non-abs. If interested, I can check for details. $60+ shipping
Starter motor. Worked after a cleaning and burnishing, but probably should get new brushes. $20 + shipping
'91 K75 non abs front wheel, Y spoke, Black. Bent, with lateral runout, but no apparent radial runout. Easily straightened by a machine shop. Best offer.
Bolts. Lots of them, from the whole engine.
Clutch: Good shape plate. Best offer.
Clutch pressure plate: good shape. Best offer.
Shoot me a PM if anyone is interested. May be interested in trades for other K bike stuff, gear, etc.
I am located in Berkeley and Marin, so I can meet up to save on shipping.
